BENIGN PIGMENTED LESIONS

Melanocytic naevi

Whilst it is possible to diminish or remove moles by laser, it is generally not advisable, as this method does not allow for histological analysis. Although the pigment is removed from the mole, the cells remain, and have the potential to cause malignancy down the track. More importantly, it removes the signs that assist in monitoring changing moles for the purpose of melanoma surveillance.

Elliptical excision or shave removal are two commonly used techniques to surgically remove moles. Both methods allow for histological analysis of the naevi to ensure that the melanocytes are benign.

Seborrhoeic keratoses

Seborrhoeic keratoses are very common skin lesions which generally increase in frequency with age. They often have a rough, slightly oily (seborrhoeic) feel. Seborrhoeic keratoses can vary from a light brown colour, to a very dark brown. If the lesion becomes irritated, they can appear red.

Seborrhoeic keratoses are harmless, and do not need to be removed. If you find them unsightly, discuss with your dermatologist how we may be able to reduce them for you. Treatment methods include cryotherapy (freezing), curettage (surgical scraping), or laser (pigment or resurfacing).

Skin tags

Skin tags are raised fleshy outgrowths of skin that are totally harmless. They tend to increase in number with age, but can be associated with areas of chaffing (neck, inner thighs, armpits), and also tend to increase in people who are overweight, or have diabetes.

Skin tags can be removed by various methods including:

Minor surgery (snipping with scissors)

Liquid nitrogen

Fine wire diathermy

CO2 laser

seborrhoeic keratosis

benign naevus

cafe au lait macule

Café Au LaitMacules

These are common, coffee coloured flat macules on the skin. Many children have 1 or 2 of these lesions, which is within normal limits. Having six or more may imply an association with other genetic syndromes.
